Be it known that ii, JOHN Hnen'rreonn, e citizen of the United States, and o. resident of Allentown, in the county of Lehigh and Stnte oi Pennsylvanie, lieve invented certain new end useful improvements in Speeder-Cones, of which the 'foilowing in e specification.

'iiie invention `reietes to n speeder cone., nn element frequently ernployedin connection with cement-mills. Where-in there are generally tivo pairs or' such cones, the coinpnnions or' each pair being relatively reversed, so tliet fingers thereon intermesh, seid two pairs of cones being geared together by ebelt passing around the seine ettlieir internesiiing portions, the cones being in coection relation with suitable dri ving provision, whereby they will serve for speeding t'ne kilns comrnoniy termed roosters the zii-rangement being suoli that if the cement-rock is roasted too fest then the kiln is run fester, or in the event of the roasting not being sufficiently vivorous then the kilns ere to be run proportionately slower.

in the torni oi e specder-cone in vogue the rim of the conc, together with its hub and nearing portion, nrc ellmede in n single metal casting', with the result tiret When the beern ing' portion becomes Worn, which occurs in e comparatively -sliortperiod of time and loetore the rest of the cone becomes impaired for service, the entire costing becomes useless,

'thereby not only entailinge' serious loss by reason of the expense of :in ontirelynew conc, but also involving n considerable loss both of time and money on account of the necessity for stopping the operation of the mill Wnile the damaged cone is removed sind n new one adjusted.

ldy niy invention l ren'xedy the diiculties noted and at tine same time provide nhighly' durable end eiiicient speeder=cone.

In the accompanying drawings, forming port of this specification, Figure 1 is e, verticel longitudinal sectionnl view illustrating generally tile forni oi' speeder-cone heretofore used. Fig. 2 is e similar View or' e speedercone embodying my invention. Fig. 3 isn transverse section, on en enlarged seele, of the improved specdleioone, 'the section loeing;`

teken in the piene indicetedby the breiten line 3 3, Fig. 2, looking toward tne rim thereof.

Similar reference olierecters ere employed to designate corresponding ports in the several figures of tne' drawings wherein they occur.v s

Y in the construction exemplified in Fig. l, which, as lociore intimated, represents the forni of Speeder-cone previously in use, the rim A., .its hub E, and the beeringportion C ere nil embodied in e. single casting, the portion C being of iess diameter than the nulo nand provided with the end flange c, whereby nn annuler recess is provided for the reception ci e spiit collar serving to retain the cone in its bearing position in the apparatus, e fibrous washer being generally interposed be tween such coller and the shoulder I), presented by the end oi' tlie hub.; Centrally through the liulo and ben-ring portion is n longitudinal passa-ge l), bovini?,n e lreywny d for the reception oi' the keyed slie'ft on which seid cone and its interineshing companion are to be mounted.

A cone or' the cnnrecter described and in good 'condition cnn be adjusted in position and will ordinarily serve for s period varying from four to eight months, the service during n portion of which will be unsatisfactory, due to increasing weer of the bearing, portion. When thc letter finally becomes unduly Worn, the entire cone, notwithstanding the fact that the other portions are still uniznpnired, hes to be removed and the entire article discarded, e completely new cone being employed to replace that removed.

' it is at the period when the bearing portion -is rendered unservicenble that tlieimportence and velue of my invention is realized. instead of entirely discarding the Worn cone citer the sinne isreinoved the bearing portion C, with its flange, is severed from the hubfiush with the siioulderthereoi, as indicated by the dotted line o, Fig. l, end the interior of the hub tiren bored to present en enlarged recess,l es indicated by the dotted lines o' d, also in seid figure, lenving sutcient metal et the inner end or' the recess to provide a seating o end avoiding weakening; of the rnetel. et the `lunction of .the heb 'with the neck A' ot the rim.

IOO.

An independent bearing portion (lof either steel or wrought or malleable iron, is then adjusted to the hub, said portion C `embodying parts corresponding with those oi' the bearing portion C previously severed from the hub, with the addition oit' an -inner cylindrical extension C2 of a diameter and length permitting it 'to snugly lit Within the hub-recess with one end c bottorning against the seating c. The portion C' and its extension C2 have a central longitudinal passage D', provided with a key. Way d', which are of such size and disposition that they register with the remaining end of tl21e passage D and keyway din the seating e. or bushing in the hub for the reception of the keyed shaft.v

Three equidistantly located openings are radially-tapped through the hub and into the bushing for theintroduction of machinescrews which rigidly connect said hub and bushing together, the employment of three screws serving to more uniformly distribute the points of connection for withstanding tor sional than would be the case were only two such connections established at diametrically opposite points. Furthermore, in addition to securing such uniform distribution of the fastening-screws the specific number and disposition of the latter permits the connection to be made with openings vand screws or' appropriate length without any one of the screwopenings intersecting the keyway, or objec- 'tionably weakening the metal oi' the bushing in the vicinityof said way.

' With a view of preventing the outer end oi' the hub from v becoming worn by :trictional Acontact with the split sleeve employed for securing the lSpeeder-cone in position the bushing C is of such length that an annular depression is Aformed between the shoulder b, presented by the hub end, and a shoulder c', constituted by the inner end of the body proper of the bearing portion C', the said depression being provided for the interposition of annu# lar WasherE, of chilled or otherwise hardened steel, the screw-openings in the hub and bushing being so located that when theparts are connected the washer E will be firmly clamped between the shoulders b and c, thereby insurtion, and consequently avoiding any wear of The extension C2 thus becomes a sleeve` either, as might be occasioned were the plate free to turn. l/Vhatever wear is incurred is sustained by the exposed side of the washer lt, and this can manifestly be superseded by one of similar character when rerpiisite.

From the foregoing description it will he.

readily appreciated that the featuresembodying n1 y invention are not only extremely sun ple, but will result in great saving ol" both time and money in the service for which they longitudinal cylindrical recess terl'ninated at its inner end by a seating presented by the metal at the junction of the hub with the rimq said seating having a central opening' with a keyway, and an independent bearing portion provided with an integral cylindrical bushing snugly located within said recess, the said portion and bushing having 'a longitudi nal passage and keyway registering with the opening, and keyway in the seating,and means for rigidly connecting the hub and bushing.

2; A Speeder-cone comprising a casting eni bodying a rim and hule, the latter containing ai longitudinabcylindrical recess terminated at its inner end by a seating presented by the metal at the junction of the hub with the rim, said seating containing a central opening with a keyway; and an independent bearing por tion having a b ody larger in diameter than the hub-recess, and provided with an integral cylindrical bushing snugly located within and cxtending'beyond said recess, the said. portion and bushing having a longitud nal passage and keyway registering withthe opening and keyway inthe seating, a hardened metal Washer interposed between the hub end and body of the bearing portion, and means i'or rigidly connecting said hub and bushing and retaining the washer in a clamped position.
